Androidx机器人配置

Question

我正在尝试在项目中使用Robolectric，但遇到了障碍，不知道如何解决。我认为这是一个配置问题，因为我什至无法运行最基本的测试。

这里是我的依赖项；

implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
implementation "org.jetbrains.kotlin:kotlin-reflect:$kotlin_version"
implementation 'androidx.appcompat:appcompat:1.1.0'
implementation 'androidx.core:core-ktx:1.3.0'
implementation 'androidx.legacy:legacy-support-v4:1.0.0'
implementation 'com.google.android.material:material:1.1.0'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
implementation 'androidx.navigation:navigation-fragment:2.2.2'
implementation 'androidx.navigation:navigation-ui:2.2.2'
implementation 'androidx.lifecycle:lifecycle-extensions:2.2.0'
implementation 'androidx.navigation:navigation-fragment-ktx:2.2.2'
implementation 'androidx.navigation:navigation-ui-ktx:2.2.2'
implementation 'androidx.preference:preference:1.1.1'
implementation 'com.google.code.gson:gson:2.8.6'
implementation 'com.google.guava:guava:28.2-android'
androidTestImplementation 'androidx.test:core-ktx:1.2.0'
androidTestImplementation 'androidx.test.ext:junit:1.1.1'
androidTestImplementation 'androidx.test:runner:1.2.0'
androidTestImplementation 'androidx.test:rules:1.2.0'
androidTestImplementation ('org.robolectric:robolectric:4.3.1') {
    exclude group: "org.apache.maven"
}

如果不包括排除组指令，则会引起一堆库冲突。

这是我的第一个测试；

@RunWith(RobolectricTestRunner::class)
class RoboTest {

    @Test
    fun test() {
        Thread.sleep(9000)
    }
}

当我尝试运行它时，我得到以下堆栈跟踪；

我已经尝试使用谷歌搜索，但我认为我无法找到我遇到的同样情况，我还尝试了使缓存/重新启动无效，但没有做任何事情。

有帮助吗？

Answer 1

我将文件从/test移至/androidtest（单元测试），并相应地更新了相关性；

implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
implementation "org.jetbrains.kotlin:kotlin-reflect:$kotlin_version"
implementation 'androidx.appcompat:appcompat:1.1.0'
implementation 'androidx.core:core-ktx:1.3.0'
implementation 'androidx.legacy:legacy-support-v4:1.0.0'
implementation 'com.google.android.material:material:1.1.0'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
implementation 'androidx.navigation:navigation-fragment:2.2.2'
implementation 'androidx.navigation:navigation-ui:2.2.2'
implementation 'androidx.lifecycle:lifecycle-extensions:2.2.0'
implementation 'androidx.navigation:navigation-fragment-ktx:2.2.2'
implementation 'androidx.navigation:navigation-ui-ktx:2.2.2'
implementation 'androidx.preference:preference:1.1.1'
implementation 'com.google.code.gson:gson:2.8.6'
implementation 'com.google.guava:guava:28.2-android'
/*androidTestImplementation 'androidx.test:core-ktx:1.2.0'
androidTestImplementation 'androidx.test.ext:junit:1.1.1'
androidTestImplementation 'androidx.test:runner:1.2.0'
androidTestImplementation 'androidx.test:rules:1.2.0'*/
testImplementation 'junit:junit:4.12'
testImplementation ('org.robolectric:robolectric:4.3.1')

docs中提到了该解决方案。

哦，男孩，我的脸上有鸡蛋吗？
